For some time the XFS group have been producing split patches for XFS,separating the core XFS changes from additional patches such as kdb,xattr, acl, dmapi. The split patches are released to the world withthe hope that developers and distributors will find them useful.

Read the README in each directory very carefully, the split patchformat has changed over a few kernel releases. Any questions that arecovered by the README will be ignored. There is even a 2.4.21/READMEfor the terminally impatient :).
